"My husband and I used David in the spring for the home inspection on a property we ended up purchasing. He was easy to get ahold of, available quickly, and incredibly knowledgeable. We purchased an almost 4000 square foot, 135 year old home, and David went out of his way to check every square inch of that property. He arrived early and had already checked the exterior by the time we got there to join him. He was excellent to deal with, made the process painless, and had some great advice for my husband and I as new homeowners. The follow up email with his report was detailed and included photos of every part of the house. His pricing was also very reasonable, especially considering the size of the home. Highly recommend!"

We are a full service licensed home inspection company in Massachusetts we have been in business since 1996. Owner operated, no subcontractors. Mass. Home inspectors license #153, Certified ASHI member # 2552071(American Society of Home Inspectors) certified/licensed Massachusetts pest inspector WDI registry certified. Fees quoted are based on multi factors, including property size, age and type of property. Email [email protected]

"Set up an appointment for an initial 10 minute phone call to talk about what we wanted. Tom ended up spending 25 minutes with us and answered a ton of questions. We subsequently set up an appointment for an initial pre-build inspection of the foundation, framing, roof, and windows. Tom was very thorough. He obviously knew his stuff. Pointed out several items that needed addressing before the insulation and walls went up. Couldn’t be happier with the amount of time he spent, how thorough he was and how much he listened to all my stupid questions and answered them in a language that I could understand. We will have him back before the next phase starts and probably a couple more times before we close. Anyone building a house or buying a new home would be wise to hire Tom. Great piece of mind and cheap insurance. Plus, he’s a really nice guy to boot."

Before hiring a home inspector, ask to see a sample inspection report. We post samples on our website. We do one home inspection a day. That gives us time to do a thorough inspection and answer all of your questions. We take many pictures and include them in the inspection report. We recommend that you accompany us on the inspection. When there is an issue, we talk about what the issue is and what needs to be done to fix it. After the inspection we write a detailed report that is specific to your property and that serves as an operating manual for your home. We answer follow up questions for as long as you own the home.

"Dan at Still Rivers Home Inspection was very responsive and knowledgeable explaining everything about the house and house function while we walked around for the inspection. His extensive knowledge and expertise comes through as he told me the signals he was looking for and what we saw and what we can conclude and cannot conclude. He was punctual in the inspection and the report following and provided a very detailed/comprehensive report. Overall - I would strongly recommend Dan and will be going back to him if I need another inspection any time soon."

Radon Detection and Reduction questions, answered by experts

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
